For configure low level state of charge threshold alert signaled from max17040 we add "maxim,alert-soc-level" property.

Why you skipped "maxim,max77836-battery"?
+ +Optional threshold properties : + If skipped the power up default value will be used + - maxim,alert-soc-level : The alert threshold that sets the state of + charge level where an interrupt is generated. + max17040 can be configured from 1 up to 32. + +Remembering that for the interrupt to be handled it must also be described the +information of the interruption in the node.
Just mention interrupts in optional properties, including the flags. BTW, the driver hard-codes the flags which is in contrast with DT here. Best regards, Krzysztof
+
+Example:
+
+ battery-charger@36 {
+ compatible = "maxim,max17040";
+ reg = <0x36>;
+ maxim,alert-soc-level = <10>;
+ interrupt-parent = <&gpio>;
+ interrupts = <18 IRQ_TYPE_EDGE_FALLING>;
+ };
